View Full Version : UYVY-problem

November 8, 2012, 15:48:25

I have just bought a dfk21au618 USB camera and when I try to capture a video in IC capture in UYVY-codec I get the following error message:

"Recording could not be initialized. Probably the codec you selected is not able to record, please try another one".

All the other codecs work fine. And I have selected YUY2 format.

Please help me with this!

//Best regards Johan

Hi Johan

The error message is correct, because there is no conversion available,
that converts Y800, YUY2, RGB24 and RGB32 into YUVY. That means, there is noway to capture an AVI
file using this codec together with this camera

This can be very confusing. I still do not fully understand but there is a CODEC (which is the COmpression-DECompression algorithm) and the CONTAINER. So you must select both that are compatable.

I think this means that the YUY2 compression algorithm processes the data stream in a manner that can not be stored in the YUY2 container as the YUY2 would have no way to output it correctly.
